In the study’s conclusion, its authors note that motorcyclist fatalities decline by 30 percent when mandatory helmet laws are enacted.

I'm curious how that figure was attained, and whether it was through fewer riders riding fewer miles (or if that was even considered).

I have read a lot of MC safety studies, even before the Harborview study, and have found that there are often other factors not taken into account when attributing fewer fatalities to mandatory helmet laws.

I think helmet laws make sense. If you fall off a bike at 20 mph and hit your head on the side-walk, it could lead to some injuries -- at 80, it's death

I've been in a skid at 60 mph (oil slick) and lived with some scrapes, thanks to the helmet
